An electric power distribution device sets a first threshold and a second threshold for a threshold temperature of main wires, and sets a third threshold and a fourth threshold for a threshold temperature of branch wires. In the case where a temperature of each of the main wires reaches the first threshold, all of branch wire switches provided in a branch wire distributor are shut off. Thereafter, in the case where the temperature of the main wire reaches the second threshold, each of the main wire switches, which is provided a main wire distributor, is shut off. In the case where a temperature of a certain branch wire reaches the third threshold, the corresponding branch wire switch is subjected to PWM control. Thereafter, in the case where the temperature of the branch wire reaches the fourth threshold, the corresponding branch wire switch is shut off.
